@ Ian - it does rather look like it, doesn't it... But the designs when they originally had their public consultation way, way back did look very nice. Not sure where the yellow has crept in from. I think the roofs were originally the more usual terracotta.

Well no, they will need to submit plans and demonstrate compliance with the relevant building regs before they receive building control approval. That may or may not allow uPVC. it's a brownfield site so presumably they will have different regs than if they were restoring a period property in a conservation area. They will also have far more stringent requirements with regard to energy efficiency for example, the good lord of Lewisham both gives and taketh away.......

No, I'm with Chen. Look at the body posture. He is pulling the child away from the exciting window display but looking (through his SARS mask) back at what had engaged the child's attention. He is not walking away from camera. And it did strike me as post some disaster - if only excess bleach in the water they wash their clothes with!

Thanks Patrick, always good to see your measured response to an issue. Plastics are evil and shouldn't be used anywhere?

Is it the look, I agree they look terrible. The environmental issue? Again, are you looking to remove platics from the construction industry or all man made materials....like concrete? Safety? there has been some discussion about whether they contribute to a fire spread. uPVC melts and burns, mind you wood burns.
